Inactive credit cards can negatively impact your credit score.
Factors that contribute to your credit score include repayment history, credit utilization, credit history length, credit mix, and new credit inquiries.
Not using your credit card can result in a higher credit utilization ratio and lower available credit, which can lower your credit score.
To maintain a good credit score, it is advised to use the card periodically, automate usage, monitor for inactivity clauses, and always pay on time.
